mmdet/ops/nms/src/nms_cuda.cpp: In function ‘at::Tensor nms(const at::Tensor&, float)’:
mmdet/ops/nms/src/nms_cuda.cpp:4:39: warning: ‘at::DeprecatedTypeProperties& at::Tensor::type() const’ is deprecated: Tensor.type() is deprecated. Instead use Tensor.options(), which in many cases (e.g. in a constructor) is a drop-in replacement. If you were using data from type(), that is now available from Tensor itself, so instead of tensor.type().scalar_type(), use tensor.scalar_type() instead and instead of tensor.type().backend() use tensor.device().
